Hai Rou serves as a 2000-Man Commander within the Qin military and holds the position of Deputy Infantry Commander of the Hi Shin Unit, a role he took up following Shou Sa's death. As one of the unit's oldest veterans, his service traces back to its earliest days as a mere 100-man squad. He possesses light brown skin, grey hair, and grey eyes, maintaining a beard and bearing a distinctive scar across his forehead and left cheek. He wears standard armor in battle. His initial interactions with Hi Shin Unit leader Shin were marked by skepticism and near-violent confrontation; during the Keiyou Campaign, Hai Rou mocked Taku Kei’s squad and nearly fought Shin. His perspective shifted after witnessing Shin’s combat prowess at the Battle of Dakan Plains. Facing the crushing pressure of advancing Qin forces, Hai Rou pragmatically advised his squad to use fallen soldiers' corpses to breach the Wei army’s defensive wall. Shin’s subsequent solo breach of that wall and decisive actions against the Wei chariots earned Hai Rou’s respect. Throughout campaigns, Hai Rou demonstrated pragmatism and strong survival instincts. He prioritized regrouping scattered forces during chaotic engagements, such as when the unit confronted Houken, the Zhao Commander-in-Chief. His experience often led him to advocate for measured tactics, cautioning against reckless charges in critical battles. During the Battle of Bayou, Hai Rou participated in the Hi Shin Unit’s flanking maneuver against Zhao forces under General Fuu Ki. He provided tactical assessments, calculating enemy ranks and advising on battlefield positioning. After Shin killed Fuu Ki, Hai Rou acknowledged the unit’s sacrifices. He later comforted Shin regarding their lost comrades, emphasizing the importance of honoring the dead with resolve rather than grief. Hai Rou is married and has children. His extensive military background dates to the era of the Qin War God, though details of his service before joining the Hi Shin Unit remain unspecified. His character development reflects a transition from a seasoned but initially dismissive veteran to a loyal subordinate who values Shin’s leadership. He consistently contributes to the unit’s tactical decisions and acts as a stabilizing presence during combat operations.
